Plessey acquires CamGaN spin-out company to gain novel GaN on silicon technology

The acquisition positions Plessey among the first commercial players to successfully manufacture HB LEDs on 6-inch silicon substrates.

T he newly acquired Plessey HB LED solution enables the growth of thin HB LED structures on standard, readily available, silicon substrate s. Current technologies us e silicon carbide (SiC) or sapphire substrates, which are expensive and difficult to scale-up . Plessey’s GaN-on-silicon solution offers cost reductions o f the order of 80% compared to LEDs grown on SiC or sapphire by reducing scrap rates, minimizing batch time and enabling the use of automated semiconductor processing equipment. The cost reductions will be achieved while enabling outputs in excess of 150 lumens per watt later this year – a combination that will allow Plessey to offer the most cost effective solutions in the HB LED industry.

Commenting on the significance of Plessey’s new technology, Dr John Ellis, Chief Engineer at Plessey , said: " To date, the biggest technological challenge preventing the commercialisation of HB LEDs grown on large-area silicon substrates has been the large lattice mismatch between GaN and silicon . Plessey’s new GaN-on-silicon process has overcome this challenge and our expertise combined with the intrinsic cost savings of using automated 6 inch processing equipment will position Plessey’s HB LED lighting products at the forefront of the industry. "

Professor Sir Colin Humphr eys, CBE FREng, Director of the Cambridge Centre for Gallium Nitride , Professor of Experimental Physics at the Royal Institute and co-inventor of the GaN-on-silicon technology, added: "This technology is the product of substantial R&D investment over the past decade and the plans for its commercial development within Plessey have tremendous potential . The opportunities to develop affordable smart-lighting products for domestic, medical, automotive and other applications provide a real opportunity to have a positive impact on people’s lives."

Plessey has also announced its plan to release a range of products for smart lighting concepts that incorporate existing Plessey sensing and control technologies including the award winning EPIC sensor. The smart lighting products will enable intelligent energy management, remote control, controlled dimming and automated response to ambient conditions.
